Triple Crown leaders

My boring question is one i don’t know how to find the answer to myself: what is the latest in the season that a player has led mlb in these three categories through the years? how recently has someone come remotely close to doing this, particularly in the era of expansion? thanks.

A potentially controversial sequence of events occurred late in the second half of the Packers-Falcons game when it appeared that two different players possibly threw punches that could’ve have warranted ejections.
